A hydromechanical torque sensor having several plenum chambers can be utilized to transmit torque between the driving and driven parts in the power train of a motor vehicle as well as to make necessary adjustments in a hydraulically adjustable transmission. To this end, the plenum chambers of the torque sensor can be connected to or sealed from each other. The torque sensor and the transmission can receive fluid from discrete sources or from a single source by way of suitable valves.

Torque monitoring apparatus

An apparatus which transmits torque between two flywheels mounted between the crankshaft of the internal combustion engine and the input shaft of the change-speed transmission in a motor vehicle has a composite damper system having first and second dampers which operate in series and a friction generating device which is operated with a delay following each change of the direction of angular movement of one of the flywheels relative to the other flywheel. The input element of one of the first and second dampers is the output element of the other of the first and second dampers.

Apparatus for transmitting torque between the engine and the change

An assembly for engaging and disengaging the crankshaft of an engine has a flywheel which is rotatably supported by a bearing system and is part of a first clutch. The flywheel has a second clutch for engaging and disengaging the crankshaft from the transmission shaft of a vehicle. A friction disc of the first clutch is non-rotatably connected to the crankshaft and friction linings are disposed at its opposite sides adjacent two pressure plates forming part of the flywheel and having linings cooperating with those of the friction disc. The pressure plates are axially movably but non-rotatably connected to each other and one thereof is secured to the bearing system. An operating means moves the other pressure plate axially, and a hub of the bearing system is rotatable relative to the crankshaft. A first housing part has a radially extending portion fastened to the hub, and a first diaphragm spring bears upon at least one of the pressure plates to disengage the flywheel from the crankshaft. An axially fixed pressure plate of the second clutch has axially extending arms connected to the housing part, and a friction disc of the second clutch has two linings and is fastened to the shaft. The second clutch has an axially movable pressure plate and a second housing part fastened to the axially fixed pressure plate of the second clutch. A second diaphragm spring is pivotable relative to the second housing part.
